I think advancement in speakers is similar to advancement in other electronics like TVs and computers. Many things are similar and there’s amazingly good speakers at reasonable price points.
In the active speaker space ^this^ is clearly true.
If the OP is looking for passive, then it gets more nuanced.
Also, I unfortunately live in a hifi-challenged part of the country -- the closest decent hifi dealer is nearly 3 hours away -- so I can’t just run out and listen to a bunch of new speakers.
Which area is that? Flagstaff, Idaho, or Wyoming?
The other problem is that the dealer has an advantage in that they
- have a room that is set up
- content that plays well on what they are selling.
- control of the volume knob.
Unless you bring your own content there are a lot of variables that will alter what sounds good in your space relative to theirs.
But it is worth listening. Just also worth knowing that one cannot remember sounds too well over a time gap between shops.
- Do you have your 20 year old speakers?
- What is wrong with those that you do not like?
- How big are they?
